SHD (Smart Handheld Device)
PDA this term, from 1992 made by Apple now has nearly a decade. During this time, progress in wireless communications has moved from analog to digital mode, can be transmitted not just voice (Voice), also contains the information (Data), but the price is pretty cheap that everyone can afford, so anyone can foreseeable future will inevitably personal digital assistants and communication integration, but also so that all mobile phone manufacturers have rolled out the so-called Smart Phone, the use of mobile phones and some PDA merger.
Whether PDA or Smart Phone, the future will be classified as SHD. With regard to SHD, Ge Jia market analysts have different views, such as IDC will SHD classified as Handheld Companions, Smart Phones, Vertical Application Devices three categories, one of the Handheld Companions, including PC Companion, Personal Companion, Classic Personal Digital Assistant; Vertical Application Devices refers to the Pen Tablet, Pen Notepad, Keypad Handheld; and Handheld Companions feature phones with the so-called Smart Phone. ING Barings to the SHD of the definitions much simpler, and they were divided into Data-Centric and Voice-Centric categories.
You see from the above definition, the future of information management capabilities with a portable electronic products can be called SHD, wireless phone, PDA, Tablet PC, or anything that can carry IA products, stock machine, and even Gameboy can be a SHD. As global demand for the PC started to weaken, causing domestic manufacturers are producing SHD-related products on the transition bet a certain degree of attention. IT exhibition from a growing number of PDA and Tablet PC prototypes on display can be discerned.
For the hardware and software developers for thinking about development plans at the same time, thoughts should not be placed on the PDA. How can the combination of wireless communications and Internet companies and even vertical integration, it becomes the most important part. In other words, in order to SHD as a mode of thought, not to the original PDA to develop the idea of stand-alone operation, this product only likely to increase added value, will not turn into that price war.

SHDSL (Single-pair High-speed Digital Subscriber Line)
The application of advanced modulation and echo cancellation technology in a pair of copper wires to provide a maximum of two-way 2.3Mbps (megabits per second) transmission rate and transmission distance according to select the appropriate transmission rate, the scope of services up to seven kilometers .
SHDSL is considered to replace the traditional T1, E1, as well as beyond the HDSL and IDSL of new technologies. Traditional T1, E1 erection in need of special construction, thereby limiting the timeliness of service delivery. In addition, due to T1, E1 spectrum compatibility is very poor, requiring the laying and maintenance of way line, and therefore needed to improve the user's costs.
For system operators concerned, in the absence of repeater case, T1, E1 service can provide only about 1.5 km distance, SHDSL advent will provide system operators and users a simple and inexpensive alternative.

SIGGRAPH Computer Graphics Conference
The establishment of three decades, computer graphics and interactive technologies of interest in the establishment of an organization.
The participation of members from a number of computer graphics enthusiasts, to come from all walks of life researchers, artists, developers, film producers, scientists, and professionals in various fields.
The organization sponsored SIGGRAPH per the Assembly, also held a forum around the world, the establishment of awards, education, donations, art exhibition and other activities, this year's SIGGRAPH 2003 will be held at San Jose.
The full name of the Society ACM-Association for Computer Machinery-Special Interest Group on Computer Graphics (Computer Machinery Association / computer graphics professional groups), the Taipei branch of the official by the United States in 2000 authorized the establishment of the Federation of SIGGRAPH.
